Pulmonary valve replacement after operative repair of tetralogy of Fallot: meta-analysis and meta-regression of 3,118 patients from 48 studies.

Because the real benefit of pulmonary valve replacement (PVR) in patients with repaired tetralogy of Fallot who develop pulmonary insufficiency remains unclear, it is necessary to analyze the evidence published around the world. We performed a systematic review of studies that reported data about the effect of PVR in patients with repaired tetralogy of Fallot that developed pulmonary insufficiency, until December 2012. The variables chosen to represent the benefit were both right ventricular (RV) and left ventricular measures, QRS duration, and functional class.

Risk factors for low cardiac output syndrome after coronary artery bypass grafting surgery.

Objectives: Low cardiac output syndrome (LCOS) is a serious complication after cardiac surgery and is associated with significant morbidity and mortality. The aim of this study is to identify risk factors for LCOS in patients undergoing coronary artery bypass grafting (CABG) in the Division of Cardiovascular Surgery of Pronto Socorro Cardiológico de Pernambuco - PROCAPE (Recife, PE, Brazil).

Methods: A historical prospective study comprising 605 consecutive patients operated between May 2007 and December 2010.

Perioperative mortality in diabetic patients undergoing coronary artery bypass graft surgery.

Objective: To investigate the risk factors for in-hospital death in diabetic patients undergoing isolated Coronary Artery Bypass Grafting (CABG).

Methods: We conducted a retrospective study with 305 consecutive diabetic patients undergoing CABG in the Division of Cardiovascular Surgery of our institution from April 2004 to April 2010. Univariate analysis for categorical variables was performed with the chi-square or Fisher's exact test, as appropriate.

Skeletonized internal thoracic artery is associated with lower rates of mediastinitis in elderly undergoing coronary artery bypass grafting surgery.

Background And Objectives: Mediastinitis is a serious complication of median sternotomy and is associated to significant morbidity and mortality. The aim of this study is to identify which option of harvesting internal thoracic artery (ITA), pedicled or skeletonized, is associated with lower rates of mediastinitis after coronary artery bypass grafting surgery (CABG) in elderly, in the Division of Cardiovascular Surgery of PROCAPE.

Methods: Retrospective study of 160 elderly who underwent consecutive CABG between May 2007 and June 2011.

Predictors of transfusion of packed red blood cells in coronary artery bypass grafting surgery.

Objectives: Finding predictors of blood transfusion may facilitate the most efficient approach for the use of blood bank services in coronary artery bypass grafting procedures. The aim of this retrospective study is to identify preoperative and intraoperative patient characteristics predicting the need for blood transfusion during or after CABG in our local cardiac surgical service.

Methods: 435 patients undergoing isolated first-time CABG were reviewed for their preoperative and intraoperative variables and analyzed postoperative data.

Validation of MagedanzSCORE as a predictor of mediastinitis after coronary artery bypass graft surgery.

Objective: The aim of this study is to evaluate the applicability of a new score for predicting mediastinitis - MagedanzSCORE - in patients undergoing coronary artery bypass graft (CABG) surgery in the Division of Cardiovascular Surgery of Pronto Socorro Cardiológico de Pernambuco - PROCAPE.

Methods: Retrospective study involving 500 patients operated between May/2007 and April/2010. The registers contained all the information used to calculate the MagedanzSCORE.

Skeletonized left internal thoracic artery is associated with lower rates of mediastinitis in diabetic patients.

Background: Mediastinitis is a serious complication of median sternotomy and is associated to significant morbidity and mortality. Diabetes is a feared risk factor for mediastinitis and viewed with caution by cardiovascular surgeons.

Objective: To identify risk factors for mediastinitis in diabetics undergoing CABG surgery with use of unilateral ITA in the Division of Cardiovascular Surgery of Pronto Socorro Cardiológico de Pernambuco - PROCAPE.

Risk factors for mediastinitis after coronary artery bypass grafting surgery.

Objective: Mediastinitis is a serious complication of median sternotomy and is associated to significant morbidity and mortality. The aim of this study is to identify risk factors for mediastinitis in patients undergoing coronary artery bypass grafting (CABG), without the use of bilateral internal thoracic artery (ITA), at the Division of Cardiovascular Surgery of Pronto Socorro Cardiológico de Pernambuco - PROCAPE.

Methods: A retrospective study of 500 consecutive patients operated on between May 2007 and April 2010.

EuroSCORE and mortality in coronary artery bypass graft surgery at Pernambuco Cardiologic Emergency Medical Services [Pronto Socorro Cardiológico de Pernambuco].

Objective: The aim of this study is to evaluate the applicability of EuroSCORE in patients undergoing coronary artery bypass graft (CABG) surgery at the Division of Cardiovascular Surgery of Pernambuco Cardiologic Emergency Medical Services--PROCAPE.

Methods: A retrospective study involving 500 patients operated between May 2007 and April 2010. The registers contained all the information used to calculate the EuroSCORE.
